England bowled out Sri Lanka on day two of the first Test to move into a dominant position in Galle.
Debutant Ben Foakes reached his first Test century before falling for 107 as England added 21 to their overnight total to post 342.
The tourists then produced a fine all-round bowling performance, with Moeen Ali taking 4-66, to bowl the hosts out for 203 in 68 overs.
England reached 38-0 at the close, 177 runs ahead.
Jack Leach and Adil Rashid took two wickets each for England, with seamers James Anderson and Sam Curran getting one apiece.
Sri Lanka were 64-4 at lunch before a patient partnership of 75 between Dinesh Chandimal and Angelo Mathews, which was ended when Rashid dismissed Chandimal for 33 shortly before tea.
Moeen then had Mathews caught at short leg from the first ball after tea and the final five wickets fell in 18.3 overs in the evening session. England are now in a strong position to secure their first overseas Test victory since October 2016 and end a 13-game winless run away from home.
Foakes had done the majority of the work needed to reach his century on day one by helping his team recover from 103-5 to close on 321-8, and without him England’s dominant position would not have been possible.
He had been calm throughout his first day in Test cricket and continued in that vein on day two, stroking the first ball of the day for four through extra cover.
